EE/CS 481 Spring February, 2008 University of Portland School of Engineering Overview Introduction Scorecard Additional Accomplishments Plans Issues/Concerns Conclusions

EE/CS 481 Spring February, 2008 University of Portland School of Engineering Introduction Our Robotic Arm: Approximates human hand/arm degrees of freedom Proof-of-concept for prosthetic application as well as test-bed for a mobile robotics Other projects are planned to make another arm, shoulders, etc. Fully humanoid robot, anyone?

EE/CS 481 Spring February, 2008 University of Portland School of Engineering Scorecard Previous month’s plans: –Begin construction of forearm Obtain the remaining materials to construct the hand up to the elbow Obtain our two motors Construct motor, servo, and host control boards once parts arrive Write pseudo-code for controllers –Finish TOPs doc What we did: –Obtained aluminum materials, mechanical joints, most components –Completed construction of 3 fingers; last two are nearly done –Theory of Operations document completed and approved –Servo and host controller programs designed

EE/CS 481 Spring February, 2008 University of Portland School of Engineering Additional Accomplishments We have been notified that the Printed Circuit boards are completed and have been shipped; they should arrive this week Prepared a demo with a few digital servos and the current working fingers for the engineering week expo Congressman David Wu liked our design!

EE/CS 481 Spring February, 2008 University of Portland School of Engineering Plans Complete construction of forearm and elbow –Machine the aluminum –Order large motors –Attach the servos, mounts, and motors to the forearm –Construct motor, servo, and host control boards once parts and boards arrive Complete embedded programming Should have working model by the end of the month

EE/CS 481 Spring February, 2008 University of Portland School of Engineering Milestones NumberDescriptionOriginal 10/30/07 Previous 2/4/08 Present 2/26/08 1Functional Spec Approval Product Approval Plan Approval Wrist Joint Design Completed Design Release Forearm Cavity Design Completed Elbow Joint Design Completed TOP’s Approval Circuit Boards Manufactured Wrist Joint Manufactured Forearm Cavity Manufactured Control Software Completed Founder’s Day Final Report

EE/CS 481 Spring February, 2008 University of Portland School of Engineering Concerns/Issues Concerns/issues: –Flexing of aluminum members Possible solutions: –Material needs to be tested for deformation –Laminating multiple members to increase rigidity

EE/CS 481 Spring February, 2008 University of Portland School of Engineering Conclusions The hand is nearly completed We have all materials and nearly all components and parts The hand says hello!!!
